ADJUSTABLE H ORSESHOE.

SPECIFICATION-forming part of Letters Patent No. 686,493, dated November 12, 1901.

Application filed February 5, 1901. Serial No. 46,117. (No model.)

To @ZZ whom t may concern:

Beit known thatI,GUY SIDNEY VOGT, a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented a new and useful Adjustable Horseshoe, of which the following is a specification.

This invention relates to horseshoes having removable calks, and has for its object to provide a shoe of the specied class in which the several calks are substantially formed in one piece with a frame adapted to be readily positioned and easily locked on a shoe, which is nailed to the hoof in the usual manner.

It is commonly known that the climatic conditions cause a frequentfchange in the horses shoeing and that a sharp or commonly-called rough shoe is quickly worn down. Therefore the principal object of my invention is to overcome the annoyances of frequent changes of the shoes by making substantially in one piece the several calks upon an auxiliary frame, conforming to the shape of the ordinary shoe, cushioned to prevent friction with the stationary member and at the same time forming a resilience to overcome the numbing of the animals feet while working on-hard roads or pavements and which may be securely locked into position, or at the will of the owner the calks'and auxiliary frame may be entirely removed, leaving a dull and common shoe for the horse while in the stable or pasture.

Another object of my invention is to provide a calk that can easily and quickly be detached from the shoe and sharpened by any one with a common file, thus saving the trouble and expense of a blacksmith.

With these various objects in view my invention consists in the peculiar construction of the various parts and their novel combination or arrangement, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming a part of this specication, Figure l is a perspective view of my Y invention. Fig. 2 is a bottom plan of the upper member. Fig. 3 is a perspective view of the lower or auxiliary frame detached. Figs.

4 and 5 are details on the lines 4C 4 of Fig. l

and 5 5 of Fig. 2. Fig. 6 is a detail view of one of the toe-locking pins.

In carrying out my invention I employ a horseshoe A, having on its under side channels and holes for the nails, all of which are of ordinary construction, while at the toe thereof are lugs C, integral or secured by any desired means and having central perforations to receive locking-pins D for the purpose hereinafter described.

' E designates rubber blocks or cushions, which are firmly secured in sockets of the shoe A and which projects a slight distance below its lower face and is designed to bear against the auxiliary frame F for the purpose of forming both a cushion to take up the jar from the horses hoofs and to prevent any friction and wear upon the several parts.

The shoe A is of ordinary construction, but is cut away or bifurcated at its heel ends, as at H, for the purpose of attaching thereto the hooked ends ot' the lower member F. Running transversely through the bifurcated ends H are pins I, which form attaching and locking means for the heel portion of the auxiliary frame.

The auxiliary frame F or lower shoe has formed in its toe portion recesses K to receive the lugs C. The inner and outer walls L and M of said recesses are provided with alining apertures N, adapted to receive the locking-pins D, which also pass through openings in the lugs C, thereby forming a secure and effective locking means for the two shoes.v

O indicates the reduced end of the lower shoe, which terminates in a hook-shaped portion P, forming the locking means for the heel ends of the two shoes, as clearly illustrated in the accompanying drawings.

Q indicates three lugs, one at the toe and one on each side of the lower or auxiliary frame, said lugs projecting a slight distance above the upper face of the auxiliary'frame, reducing to a minimum all side movement between the two shoes.

Located on the under side of the auxiliary frame are the calks R and- S. These calks are of ordinary construction and can be secured integral therewith or fastened in any manner desired.

The locking-pins D are passed through the apertures in the auxiliary frame F and also through the lugs C, and in order to hold the pins in posit-ion I employ split keys T, which pass through the inner ends of the pins.

The main shoe A can be used when the animal is in the stable or pasture; but when placed upon the road or desired for any kind of work the supplemental shoe F is attached.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an article of the kind described, the combination, with the main or upper shoe having depending toe-lugs and bifurcated heel portions, said bifurcated portions carrying cross-pins, of the auxiliary or supplemental shoe having hooked rear ends adapted to engage the pins, and recessed at the forward end to receive the lugs of the main shoe, and

means for fastening the said lugs in lthe red cesses, substantially as shown and described.

2. The combination, with the main shoe having depending toe-lugs and bifurcated heel portions carrying the cross-pins, of the lower or supplemental shoe or frame having reduced ends hooked as described and adapted for engagement with the pins carried by the bifurcated ends, the forward portion of said supplemental shoe being recessed or soeketed and adapted to receive the depending lugs of the main shoe, the pins for locking the said shoes together, and the interposed cushions, all arranged and adapted to operate substantially as shown and described.
